This reminds me of Gresham's Law: "bad money drives out good." But here, the result is inverted—efficient replicators drive out the less efficient.
(Several places online list "durability; portability; divisibility; scarcity; fungibility; and acceptability" as the key characteristics of "good money." Difficulty-of-replication pertains to the "scarcity" characteristic: if it's easy to duplicate, that makes it "bad" money, not "good" money.)
